Which organ regulates the level of sugar in the blood by secreting insulin?

Explanation:
Insulin control of blood sugar comes from the pancreas. The pancreas contains beta cells in the islets of Langerhans that sense rising blood glucose and release insulin. Insulin then signals muscles and fat to take up glucose and promotes storage of excess glucose as glycogen in the liver, while also dampening glucose production by the liver. This coordinated action lowers blood sugar levels. The liver helps manage glucose storage and release, but it does not secrete insulin. The stomach and gallbladder are involved in digestion and bile storage, not hormone secretion that regulates blood glucose.
